Required: Determine for the year: 1. The fixed, variable, and total factory overhead application rates (per machine hour). (Round your answers to 2 decimal places.) 2. The total flexible budget, for factory overhead cost based on output achieved in 2022. 3. The production volume variance. State whether this variance was favorable (F) or unfavorable (U). 4. The total overhead spending variance. State whether this variance was favorable (F) or unfavorable (U). 5. The overhead efficiency variance. State whether this variance was favorable (F) or unfavorable (U). 6. The variable overhead spending variance and the fixed overhead spending variance. State whether each variance is favorable (F) or unfavorable (U)
